Generate formatter defaults from the version catalog

[builtbyjuls]

Closes #2705.

Needs to check the other versions as well, replace all related usages.

Thanks. To confirm, should I generate constants for every catalog-backed formatter/runtime default in lib and replace their usages across lib and the plugins, while keeping compatibility thresholds and intentionally older compile pins hardcoded?

I found four catalog/default mismatches: Gson 2.14.0/2.13.2, Jackson YAML 2.20.1/2.14.1, Cleanthat 2.24/2.25, and Palantir 1.1.0/2.80.0. Including those would change or downgrade current defaults. Should this PR reconcile those too?

Thanks, @Goooler. I updated the PR to cover the full mandatory scope you outlined.

• Generated package-private defaults for the catalog-backed formatter runtimes, including the 11 ready items.
• Added the separate Palantir 2.80.0 runtime default while keeping its 1.1.0 compile-only pin.
• Updated Cleanthat to 2.25, Gson to 2.14.0, and Jackson YAML to the shared Jackson 2.20.1 version.
• Made both Gradle and Maven JSON Patch defaults follow JsonPatchStep.defaultVersion().
• Kept compatibility thresholds, historical test versions, and intentional compile-only pins hardcoded.
• Left the optional formatters and NPM/native/P2 items out of scope.
• Added the requested Gson entry to CHANGES.md.

All affected formatter and plugin tests pass. The aggregate build encountered only an external Gradle download timeout and a parallel P2 lock collision; all three affected test methods passed when rerun alone. An independent post-change review also approved the implementation with no findings.
